Redis setup help

I have some issues setting up redis cache in openlitespeed and centos8. I followed this guide to setup cache.
I need to create a INI file but not sure about the file path for openlitespeed.

sudo echo "" > /etc/php/7.x/apache2/conf.d/redis.ini

the one given in the guide was for apache. can anyone please give me the correct for for openlitespeed ?
